Pacala chairs national committee calling for immediate push for CO2-removal technology

October 30, 2018

Now on the Princeton University homepage: A National Academy of Sciences committee chaired by PEI associated faculty member Stephen Pacala reported that the escalating effects of climate change demand a research initiative to develop and launch "negative emissions technologies" that remove and sequester carbon dioxide directly from the air. Pacala is the Frederick D. Petrie Professor of Ecology and Evolutionary Biology, co-director of PEI's Carbon Mitigation Initiative, and a past director of PEI....

Matteo, Megan and Steve publish new paper in Ecology Letters: Predicting shifts in the functional composition of tropical forests under increased drought and CO2 from trade‐offs among plant hydraulic traits

August 20, 2018
Full Paper Abstract: The mechanisms governing tree drought mortality and recovery remain a subject of inquiry and active debate given their role in the terrestrial carbon cycle and their concomitant impact on climate change. Counter‐intuitively, many trees do not die during the drought itself. Indeed, observations globally have documented that trees often grow for several years after drought before mortality. A combination of meta‐...

New Study Finds U.S. Oil and Gas Methane Emissions Are 60 Percent Higher Than EPA Reports

June 25, 2018
As a new study reveals US oil and gas methane emissions are 60% higher than previously thought, it’s crucial that companies and governments see the opportunity in curbing waste of this valuable resource.  https://www.edf.org/media/new-study-finds-us-oil-and-gas-methane-emissions-are-60-percent-higher-epa-reports-0 Read more about New Study Finds U.S. Oil and Gas Methane Emissions Are 60 Percent Higher Than EPA Reports

New Matteo's publication in Nature Communications: Resource acquisition and reproductive strategies of tropical forest in response to the El Niño–Southern Oscillation

March 6, 2018

Full paper. The El Niño–Southern Oscillation (ENSO) is the largest source of interannual climate variability in much of the tropics. We hypothesize that tropical plants exhibit interannual variation in reproduction and resource acquisition strategies driven by ENSO that mirrors their seasonal responses. We analyze the relationship of leaf and seed fall to climate variation over 30 years in a seasonally dry tropical forest in Panama where El...

Kaz and Steve published "The role of succession in the evolution of flammability"

February 8, 2018

In this paper Kaz presents the model he was working at during the first years of his PhD in the Pacala Lab on arrested succession and he evolutionarily stable strategy level of flammability in fire-prone vegetation systems. 

Fire-prone ecosystems contain plants that are both fire-adapted and flammable. It has been hypothesized that these plants were under selection to become more flammable, but it is unclear whether this could be adaptive...

Steve, Sam Rabin (Graduate alumni) and some colaborators from the GFDL LM4 team just published "A fire model with distinct crop, pasture, and non-agricultural burning"

February 4, 2018
This study just published in the journal of Geoscientific Model Development describes and evaluates the Fire Including Natural & Agricultural Lands model (FINAL) which, for the first time, explicitly simulates cropland and pasture management fires separately from non-agricultural fires. FINAL represents an important step in the development of global fire models, and offers a strategy for fire models to consider human-driven fire regimes on...

STEVE & ANNA'S NEW PUB CAME OUT TODAY! Differential declines in Alaskan boreal forest vitality related to climate and competition

November 15, 2017
LINK TO PUBLICATION Rapid warming and changes in water availability at high latitudes alter resource abundance, tree competition, and disturbance regimes. While these changes are expected to disrupt the functioning of boreal forests, their ultimate implications for forest composition are uncertain. In particular, recent site-level studies of the Alaskan boreal forest have reported both increases and... Read more about STEVE & ANNA'S NEW PUB CAME OUT TODAY!
